Hi guys, have a listen to this video.
My exhaust is perfectly sealed but it sounds like it blown especially when cold. It sounds worse in person and I'm actually embarrassed to start it up in from of people!

Tried ur coil pack? May be ur down pipe it has the mesh over it, it may have split.

 

[andycupra]

sounds like something loose. like cat heat shield or joint.

I've not tried coilpack mate and the downpipe and de-cat pipe are only 2 months old and leak test around all joints and flexi showed nothing.

I've heard people going on about they're SAI making they're car sound like a tractor because the pump wears out. But, I don't know if the LCR even has SAI?
The noise definetly sounds like it's inside the exhaust around the de-cat pipe area but it just doesn't make sense.
The car also runs amazing

I'd need to really have a look myself mate, if your up for it I can meet you tomorrow over at u pull it? Need to go over there anyway?

 

[LCR]

That would be great bud, I finish work at 330 so I could be down there for about 430ish. If u can't make that time it's no probs at all. I should eventually figure it out haha

Mate I can be down there for 4.30pm that's perfect, I'll message you on this at 3/3.30pm to make sure ur coming, I'll be in a silver cupra also.

 

[Bigjohn84]

You got a vag com?

 

[LCR]

Sweet, thank you very much, I don't have a vag com unfortunately.
Another reason I don't think the exhaust is the problem is because before I changed it to de-cat and 3" DP, it made the same noise. Bloody strange! 07753112183 is my number just in case I don't get 3G at work tomorrow

Backbox baffles?

It did cross my mind mate but the noise I definetly from the mid to front of exhaust. I thinking it may be my oil pick up pipe which I haven't replaced before

It's the decat.

Mines did this when i fitted my decat pipe. Sounds like it's blown and sounds shite at low revs

 

[LCR]

Have you checked turbo to manifold gasket, and have you checked manifold is not cracked?
